Timmia Hedw. – Toppmosar

Uppréttir blaðmosar. Fremur sterklegir og stórvaxnir mosar í gulgrænum þúfum á jarðvegi eða klettum og í gjótum á rökum stöðum, oft í skugga.

Blöð eru stór, 5-10 mm á lengd, og mynda aðlægt, litlaust, gulleitt eða rauðleitt slíður að stöngli. Rif er sterklegt og endar rétt neðan við blaðodd, en gengur jafnan lítið eitt fram úr á einni sjaldgæfri tegund; oft vörtótt eða tennt á baki. Blöð tennt framan til. Frumur í blöðku litlar, ferhyrndar eða sexhyrndar, um 10 µm á breidd, gúlpnar eða vörtóttar. Frumur í slíðri rétthyrndar, langar eða striklaga, sléttar eða vörtóttar á bakhlið.

Ein tegund, T. bavarica, er tvíkynja en sjaldan með gróhirzlur; hinar eru einkynja og því aðeins örsjaldan eða aldrei með gróhirzlur.

Timmia tegundir minna um sumt á Polytrichum, Polytricastrum og Pogonatum tegundir, en þær eru allar með langræmur á efra borði blaða, svo að þær eru auðgreindar frá.

Ættkvíslarheitið Timmia Hedw. er til heiðurs þýzkum lyfjafræðingi, Joachim Christian Timm (1734-1805).

Greiningarlykill að tegundum:

1 Efstu blöð á plöntunni eru um það bil jafnlöng og öll önnur blöð ………………. 2

2 Slíður rauðgult eða rauðbrúnt. Plöntur einkynja …………….. T. austriaca
2 Slíður litlaust. Plöntur tvíkynja ……………………….. T. bavarica

3 Rif endar rétt neðan við blaðodd, vörtótt á baki. Blaðfrumur 10-15 µm á breidd .. T. norvegica
3 Rif nær oft lítið eitt fram úr blöðku, nær slétt á baki. Blaðfrumur 6-9 µm á breidd … T. comata
Timmia austriaca Hedw. – hagatoppur (all algengur)
Timmia bavarica Hessl. – gjótutoppur (mjög sjaldgæfur)
Timmia comata Lindb. et Arnell – skorutoppur (mjög sjaldgæfur)
